Subsequent Events [Text Block]	NOTE 9. SUBSEQUENT EVENTS Facility sale We entered into an agreement on February 23, 2021 with a third-party agent to sell our facility in Merrifield, MN and some related assets. A liquidation auction was completed in April of 2021 for the Merrifield facility. We closed on the sale of the facility in July 2021 with a gain less than $100. PPP and Employee Retention Credit (ERC) In the third quarter of 2021, we have applied for forgiveness for the $6.1 million Promissory Note under the PPP. We will continue to treat this Promissory Note as debt until forgiveness is granted. In addition, we have applied for the ERC credit for the first and second quarters of 2021. If the application is successful, we expect to receive approximately $5 million in fiscal 2021.
